ABSTRACT:
The invention concerns a method of receiving a signal transmitted by a transmitter (k) and arriving at an array of antennae (300) after having propagated along a plurality of paths (i), comprising a filtering stage (310k) decomposing each antenna signal into separate signals (xl,i,k) issuing from the different paths, a channel formation step (320k) forming path signals (yi,k) from the said separate signals by means of a first set of complex coefficients (bl,i,k), a combination step (340k) linearly combining the said path signals by means of a second set of complex coefficients (ci,k) in order to supply a combined signal (zk), the method being characterized in that a plurality of first error signals (ε′i,k) are formed (331k) between a reference value (qk) of the signal transmitted and the said path signals (yi,k) and in that a second error signal (ε″k) is formed (351k) between the said reference value and the said combined signal (zk), the first and second sets of complex coefficients being adapted (330k, 350k) so as to respectively minimize the root mean square values of the first signals and of the second error signal.
